Time Keeps On Slippin' Assignment
1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted.
The Gregorian Calendar. It was introduced to the public by Pope Gregory XIII and is accepted because it has improvements from the previously accepted calendar, which was the Julian Calendar.
2) What is a leap year?
Every four years an extra day is added between February 28 and March 1 to compensate for the earth's rotation, which is 365.25 days a year.
3) List three other types of calendars used and how they set up their calendar (ex. Lunar).
Lunar - a calendar based on the cycle of the moon.
Solar - a calendar based on the cycle of seasons. Years in a solar calendar could be only months in reference to the Gregorian Calendar.
Lunisolar - this calendar trires to be both a lunar and a solar calendar but is more succesful in being a solar calendar than a lunar one.
4) What is BC?
It stands for "Before Christ"; used to indicate the years before Christ's birth.
5) What is BCE?
Stands for "Before the Common Era and indicates the exact same time as BC.
6) What is AD?
Stands for "Anno Domini", a latin phrase meaning "The Year of Our Lord." It is used for the years after Jesus' birth.
7) What is CE?
Stands for "Common Era"; the purpose is the exact same as AD.
8) What is MYA?
Stands for "Million Years Ago."
9) According to the timeline site how many periods of when are there and list time.
Here are the 22 periods:
14000 MYA -- The Big Bang: The Formation of the Universe
4600 MYA -- Formation of the Earth
543 MYA-409 MYA -- Cambrian: First Life on Earth
290 MYA-248 MYA -- Permian: Largest Mass Extinction
245 MYA-65 MYA -- Mesozoic: Dinosaur Age
65 MYA -- Cenozoic: Mammal Age
5 MYA-2500 BC -- Human Era
70000 BC-8000 BC -- Ice Age: Extinction of Large Animals
9000 BC-4500 BC -- Neolithic: First Permanent Settlements
3200 BC-1200 BC -- Bronze Age: First Pharaohs
1200 BC-332 BC -- Iron Age: Start of the Trojan War
332 BC-63 BC -- Hellenistic Period
63 BC-476 AD -- Roman Period
330 AD-1453 AD -- Byzantine Period
476 AD-1350 AD -- Middle Ages
10) What is an eon, epoch, era, and age?
Eon - An extremely long time
Epoch - The beginning of an era
Era - A long period of time determined by the start and end of an event
Age - A period in history marked by a historic event or accomplishment
11) List three ancient calendars
Aztec Calendar, Mayan Calendar, and Babylonian Calendar.
12) List two ancient clocks and how they worked.
Water Clock - Time is measured by the inflow or outflow of water. The water is then measured.
Sundial - It determines the time of day by the possition of the sun.
13) What was a revolution of timekeeping?
In the early 16th century, Peter Henlein invented spring-powered clocks. These clocks replaced heavy weights, which allowed portable, smaller watches.
14) What allows for standard more accurate clocks?
Some atoms are consistently stable and constitute a potential pendulum, that has a reproducible rate.
15) What are time zones?
Time zones are made to compensate the earth's rotation around the sun, because if the whole world was on the same time, it could possibly be 4 AM in the middle of the day. Each time zone is 15 degrees wide on average.
16) What is the prime meridian?
The prime meridian is the line of longitude that is 0 degrees. It divides the eastern and western hemispheres and reaches from the north pole to the south pole.
17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii?
Toronto -- 11:00 AM
London -- 4:00 PM
Moscow -- 8:00 PM
Tokyo -- 1:00 AM
Hawaii -- 6:00 AM
18) What is Daylight Saving Time? Do we use this in Saskatchewan?
Dalight Saving Time time is used twice a year. Once in the spring and another in the fall to make up for the position of the sun. We don't use this method in Saskatchewan because the time zone spilts in the middle of our province. But we doo change time zones every daylight savings.
19) Is there a year zero?
No.
20) Are we starting a new decade in 2010 or 2011?
2011
21) What is linear time?
Linear time is the concept that no matter how you feel, what you do, or how you look at time, it does not change as a result.
22) What is cyclical time?
Cyclical time is the theory that time moves in cycles, such as the lunar cycle.
